Overview

The Lumishore 010-04501-00 is a surface-mount underwater LED light that outputs blue light from a compact, low-profile housing. It runs on 12V DC only (10.5 to 15V) and carries an IP68 water-ingress rating for continuous underwater use.

On the outside, the light face is 70 mm (2.75 in) with a 17 mm (0.67 in) profile, which helps when space is tight on a transom or hull side. Light spread is a 90° beam, and the housing uses a marine bronze body with a borosilicate glass lens. It is rated for vessels up to 7.5 m (25 ft).

Key features

• 12V DC only (10.5 to 15V) with max current draw of 2.5A for power planning
• IP68-rated enclosure for underwater mounting
• Marine bronze body with a borosilicate glass lens
• 90° beam angle for a wide light pool off the stern or along the hull side
• 70 mm (2.75 in) face with a 17 mm (0.67 in) profile for tighter mounting areas
• 2 m (6 ft 6 in) cable as standard, with extension possible using proper gauge to control voltage drop
• Simple 2-wire installation for on/off control, with support for ECLIPSE Command Center control (zone control and dimming when connected)
• Isolation kit required when installing on conductive hull materials

Installation and setup

Mount the light on a flat section of transom or hull side where you can reach the inside of the hull for cable routing and sealing. For underwater illumination, placement about 100 to 300 mm (4 to 12 in) below the minimum load waterline keeps the beam in the water without putting the fixture too close to the surface.

The cable gland requires a recessed cut-out: a 13.5 mm (17/32 in) hole cut to a depth of about 15 mm so the light can sit flush. Use a marine sealant such as 3M 4200 or an equivalent, hand-tighten the mounting screws, and avoid power tools so the housing seats evenly. If you are installing three or more lights, even spacing of roughly 2.5 to 3 ft helps keep the light pool consistent.

Electrical and system integration

Plan the cable route before fastening the light and keep all connections waterproof. Each light should be individually fused with a 4A fuse, and wire sizing should follow ABYC guidance for voltage drop of 3% or less on critical circuits. The unit is 12V only, so it should not be tied into 24V systems without an appropriate, correctly sized DC-DC solution.

What’s included

• Surface-mount underwater LED light
• 3 marine bronze mounting screws

Maintenance and care

Check the light body and lens area regularly for marine growth and clean with a soft cloth or a soft bristled brush. Avoid abrasive pads and cleaners that contain solvents, acids, or alkalis. Do not use pressure washing or sandblasting equipment on the fixture.
